Izibophelelo zoomatshini ngamagorha angaziwayo obunjineli bale mihla, abambe kunye yonke into ukusuka kwizixhobo ezincinci zombane ukuya koomatshini abakhulu bemizi-mveliso. Phakathi kwezi, i-screws esetyenzisiweyo ithatha i-niche ekhethekileyo-engenantloko, i-compact, kwaye yenzelwe ukuhambisa i-torque okanye ukulungisa izinto ezinxulumene nomnye ngaphandle kwamantongomane angaphandle. Ngaphakathi kusapho olwahlukeneyo lwezikrufu zeseti, umahluko onomcaba ugqamile ngokukwazi kwawo ukukhusela iindawo ngaphandle kokutshatisa umphezulu wokukhwelana, oko kuyenza ilungele usetyenziso apho ukuchaneka kunye nokunyaniseka komphezulu kubaluleke kakhulu. Xa yenziwe kwi-M12.9 grade carbon steel, le fastener ethobekileyo iguqulwa ibe yinto ephezulu yokusebenza ekwaziyo ukumelana nemithwalo enzima kakhulu, i-vibrations, kunye ne-torque-eyenza ibe yinto efunekayo kumashishini afuna amandla angenakulinganiswa kunye nokuthembeka.  

I-screw ene-flat-ended set screw ichazwa ngumzimba wayo ongenantloko, i-shaft ene-threaded, kunye ne-flat, i-perpendicular tip kwelinye icala, idityaniswe ne-socket ye-drive (ngokuqhelekileyo i-hex) kwelinye. Ngokungafaniyo nezikrufu zeseti yekomityi, ezizinzisa kwishafti ukwenza isitshixo esitshixayo, izikrufu ezisicaba zixhomekeke kukruxuko phakathi kwencam emcaba kunye nomphezulu wokukhwelana ukuze kubambe amacandelo endaweni. Olu luyilo lubonelela ngeenzuzo ezimbini ezibalulekileyo: okokuqala, luphepha ukonakalisa i-shaft okanye icandelo (i-boon yamalungu asebenzisekayo), kwaye okwesibini, isasaza amandla okuBamba kwindawo enkulu, ukunciphisa uxinzelelo loxinzelelo.  

Ukungabikho kwentloko kuvumela isikrufu ukuba sihlale sigungxulwe kunye okanye ngaphantsi komphezulu wecandelo elikhuselayo, lisenza ukuba lilungele izicelo ezinendawo encinci okanye apho kufuneka iprofayili egudileyo. Ngokomzekelo, kwibhokisi yegiya, i-screw ene-flat-ended set screw inokuphinda ibuyele kwi-hub ye-gear, ukuqinisekisa ukuba akukho protrusions eziphazamisayo kwiindawo ezikufutshane.  

Unyango lobushushu lilitye lembombo lenqanaba le-12.9:  

1. Ukucima: I-screw ishushu kwi-850-900 ° C (1562-1652 ° F) kwaye ipholile ngokukhawuleza kwioli (ukuphepha ukuqhekeka). Le nkqubo iguqula i-microstructure yensimbi ibe yi-martensite, isigaba esinzima kodwa esinqabileyo.  

2. I-Tempering: I-screw ecinyiweyo ifudunyezwa kwi-500-600 ° C (932-1112 ° F) kwaye ibanjwe ixesha elithile ngaphambi kokupholisa. Eli nyathelo linciphisa i-brittleness ngelixa ligcina amandla aphezulu, okubangela indibaniselwano elinganayo yobunzima (38-42 HRC) kunye nokuqina.  

Indibaniselwano eyodwa yokuchaneka kwencam-mcaba kunye namandla omgangatho we-12.9 yenza ezi zikrufu zilungele usetyenziso olufunwayo kuwo wonke amashishini:  

Kwiibhokisi zegiya ezinomthwalo onzima, i-M12.9 enesiphelo esisicaba siseti izikrufu ezikhusela iigiya ze-helical ukuya kwi-shafts, zihambisa i-torque ukuya kwi-500 Nm ngaphandle kokutyibilika. Ngokomzekelo, i-20-tooth gear kwi-gearbox ye-conveyor ye-drive gearbox ixhomekeke kwesi sikrufu ukuze sihlale sigxininisekile kwi-shaft yayo-naphantsi kobunzima be-10-tonne imithwalo. Incam ethe tyaba iqinisekisa ukuba ibhore yegiya ihlala ingonakaliswa, ivumela ukuqhawuka lula ngexesha lokugcinwa.  

Ukuhanjiswa kwemoto yokusebenza kusebenzisa ezi zikrufu ukulungisa iihabhu ze-synchronizer kwiishafu eziphambili. Ngexesha lokutshintsha kwegiya, ii-hubs zifumana i-torque spikes ngequbuliso (ukuya kuthi ga kwi-300 Nm), kunye nokumelana nokudinwa kwebakala le-12.9 kuthintela ukuqhekeka kumawaka eeshifti. Kwiindibano ezihlukeneyo, zikhusela iigiya ezisecaleni kwimeko, ukumelana nemikhosi ejikelezayo eyenziwa ngexesha lokukhawuleza.  

I-excavators kunye ne-bulldozers isebenzisa i-M12.9 i-screws ene-flat-ended set screw ukukhusela i-hydraulic pump shafts kunye nezikhonkwane zebhakethi. La macandelo abonakaliswe kwimithwalo yothuso kunye nokungcangcazela, ngoko ke amandla esivuno esiphezulu se-screw aqinisekisa ukuba asonakalisi. Umzekelo, isikrufu se-bucket pin ye-excavator kufuneka sixhathise i-800 Nm ye-torque xa uphakamisa umthwalo weetoni ezi-5-into ye-screws ephantsi ayinakukwazi ukuyiphatha.  

Ngelixa izinto ezibalulekileyo ze-aerospace zisebenzisa i-titanium alloys, i-M12.9 i-screws ene-flat-end-ends isetyenziswa kwiirigi zokuvavanya injini. Ezi zixhobo zilinganisa iimeko zokubhabha, zisebenzisa imithwalo efikelela kwi-1200 Nm kwiindawo zenjini. I-screw's 1200 MPa amandla okuqina aqinisekisa ukuba inokumelana nale mikhosi igqithisileyo ngaphandle kokusilela.  

Imveliso ye-M12.9 ye-screws enesiphelo esisicaba ibandakanya amanyathelo angqongqo okuqinisekisa umgangatho:  

1. Umzobo wocingo: Ucingo lwentsimbi olunekhabhoni ephantsi lutsalwa ngokufa ukuze lunciphise ubukhulu balo, lunyuse amandla ngokusebenza okubandayo.  

2. Isihloko esibandayo: Ii-blanks zisikwa kwi-wire kwaye zenziwe zibe zizikhonkwane kusetyenziswa izikhonkwane zoxinzelelo oluphezulu. Le nkqubo igcina ukwakheka kweenkozo zetsimbi, ukuphucula ukunyameka kokukhathala.  

3. Ukuqengqeleka komsonto: Ukujikeleza kufa imisonto yokucinezela emzimbeni, kudala imisonto eyomeleleyo kunomatshini (ekubeni isebenza-yenza lukhuni izinto).  

4. Unyango lokutshisa: Ukucima kunye nokutshisa njengoko kuchaziwe ngaphambili.  

5. I-Surface Coating: Ukuthintela i-corrosion, izikrini zifakwe nge-zinc plating (passivated), i-oxide emnyama (i-aesthetic kunye ne-resistant-resistant), okanye i-Dacromet (ukhuseleko oluphezulu lwe-corrosion kwindawo enzima).  

Izikrufu ezigqityiweyo zeseti ezenziwe kwi-M12.9 grade carbon steel zibubungqina bokugqwesa kwezobunjineli. Uyilo lwabo oluchanekileyo kunye namandla akhethekileyo abenza babaluleke kakhulu kumashishini apho ukuthembeka kubaluleke kakhulu. Ukusuka kwiibhokisi zegiya ukuya kwizixhobo zokwakha, ezi zikrufu zidlala indima ethuleyo kodwa ebalulekileyo ekugcineni ihlabathi lethu lihamba. Ngokuqonda iipropathi zabo kunye nezenzo ezizezona zilungileyo, iinjineli zinokusebenzisa amandla azo apheleleyo ukwakha iinkqubo ezima kuvavanyo lwexesha.
